Sum = P lent out

after one year, Rs 2, 200 = P (1 + r /100 )

After 4 years  Rs 2, 800 =  P (1 + 4 r /100)

Subtract equation 1 from equation 2 :  Rs 2, 800 - RS 2, 200 = 3 P r /100
                                     P r = Rs 20,000

Substituting the value of P r in equation 1 :
           2, 200  = P + 200            So P = Rs 2,000.

             r = 20,000 / 2,000 = 10
